Product Details

The Cometic C4589-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Subaru FA20D and Toyota 4U-GSE engines. This precision-manufactured gasket features an 89.5mm bore diameter and .040" (1.0mm) compressed thickness, designed for the left-hand side cylinder bank.

Key Features:

  • Multi-Layer Steel (MLS) construction with multiple embossed stainless steel layers for maximum durability
  • 89.5mm bore diameter for precise combustion chamber sealing
  • .040" compressed thickness allows for custom compression ratio tuning
  • Viton rubber bonded to outer layers provides superior oil and coolant sealing
  • Engineered for high-performance and forced induction applications
  • Left-hand side (LHS) head gasket configuration
  • Compatible with Subaru FA20D (BRZ, 86) and Toyota 4U-GSE engines

Cometic MLS head gaskets are the choice of professional engine builders and performance enthusiasts worldwide. The advanced multi-layer design allows the gasket to recover from thermal expansion cycles while maintaining consistent clamping pressure across the entire sealing surface, making it ideal for turbocharged, supercharged, and high-compression naturally aspirated builds.
